2. Lied about it to Commander Adama, and maintained that lie for the years she served under him on Galactica.
3. Strikes superior officers (Colonel Tigh, Lee Adama).
4. Refuses to train the nuggets because she has issues about her responsibility for Zak's death. Grow the fuck up, it's not all about you.
5. "You don't have a sniper, and I'm the best shot, in or out of the cockpit."
6. Goes to shoot Tom Zarek even after it's clear that Apollo has defused the situation.
7. Sleeps with Gaius Baltar and has the bad manners to call out Apollo's name not once, but twice, during.
8. She's a poet.
9. She also could've gone pro with Pyramid- knee injury killed that. But she's still good enough that she can give a professional player like Anders a run for his money

10. Comes up with the utterly moronic plan for Galactica to abandon the civilian fleet to return to Caprica to pick up the handful of survivors she encountered- all because of Anders. Throws military common sense and caution to the winds by proposing:
10.1 That it will take ~240 jumps for Galactica to return to Caprica. As Commander Adama noted, this was optimisitic nonsense, taking no account for navigational error that would increase with every jump.
10.2 Leaving a mere handful of Vipers and one Raptor, alone, to guard the civilian fleet. The silly idiot even says "and a Raptor!" when Roslin shakes her head in disbelief at the number being proposed.
10.3 That the fleet's only defence and thousands of people be risked in such a foolish operation in the first place.
11. Has the brilliant idea of going into the Hostage Situation at Cloud 9, where she is promptly recognized (due to Ellen Tigh's reaction), and, you know, because she's The Best Shot, pulls out two pistols akimbo and starts blasting away- missing pretty much everyone, getting two Marines killed- oh- and striking Apollo in the chest by accident.
12. Gets all emo and angsty about Anders to the point that she's perpetually hungover and dismissive of nugget pilots coming to her for advice. This results directly in the death of one nugget who she in the first part gives dismissive, undetailed advice to, and in the second part fobs off on another pilot because she was too hungover.
13. Even with all this, she has the nerve to lambast Kat, continuously, for becoming addicted to stims.
14. Sleeps with Apollo while with Anders- declares she loves him after he professes the same for her.
15. The morning after, abandons Apollo, wakes Anders, and marries him.
16. Cheats on Anders in the course of their marriage (or so Anders claims in "Eye of Jupiter").
17. Gets all emo and angsty about how terrible it was to be locked up with Leoben (boo fucking hoo, you didn't have it anywhere near as bad as others) on New Caprica for four months to the point that she sows dissension amongst the crew, casting aspersions that anyone who wasn't on New Caprica can't be trusted and dismissing the efforts of the Galactica crew to rescue them as small fry. Bonus points for blowing off a sweet little kid in the same episode who just wanted a hug from her savior/ surrogate mother- apologies later don't count.
17.1 Still all emo and angsty and blows Anders off because "she's in a different place right now".
17.2 Still all emo and angsty, she blows off Gaeta's truthful explanation of everything he did for the Resistance and doesn't even think to mention it to the Circle until she taunts Gaeta mere seconds before he's about to be tossed out an airlock. Only Tyrol's level head saves Gaeta's life.
17.3 Sleeps with Anders in what is clearly a purely casual thing- the marriage is clearly dysfunctional. But has the gall to:
17.4 Taunt Apollo that he's man enough to "try and frak another man's wife" but "not fight one" in "Unfinished Business"- you know, because Starbuck's not responsible for her choice to sleep with Apollo all those months ago, right?
17.5 Starts sleeping with Apollo again after this. When asked by Apollo to divorce Anders, refuses because ... "marriage is a sacrament." You can't make this shit up. The marriage doesn't fucking work, she cheats on him willy nilly- she classifies this as merely "bending the rules".
Seriously, can anyone like this sociopathic headcase? She's easily the most detestable character in the entire show.
